RELEASE SAVEPOINT

    Description

    destroys a savepoint previously defined in the current transaction.

    Destroying a savepoint makes it unavailable as a rollback point, but it has no other user visible behavior. It does not undo the effects of commands executed after the savepoint was established. (To do that, see .) Destroying a savepoint when it is no longer needed may allow the system to reclaim some resources earlier than transaction end.

    The name of the savepoint to destroy.

    Examples

    To establish and later destroy a savepoint:

    1. BEGIN;
    2.     SAVEPOINT my_savepoint;
    3.     INSERT INTO table1 VALUES (4);

    This command conforms to the SQL standard. The standard specifies that the key word SAVEPOINT is mandatory, but HAWQ allows it to be omitted.
